Blocking images on PieFed - coming soon (peertube.wtf)

PieFed uses PDQ hashing to generate a fingerprint of an image and can use that fingerprint to detect other posts that use the same or fairly similar images, for moderation purposes. Hashes are added to a block list which stops the image from being re-posted in future.

Currently each instance maintains their own list of hashes. But in the near future it will be possible to share them so that if I see something horrific & ban it then the ban will be automatically applied to your instance too and then you won't need to see the image at all.

that sharing of hashes seems to be something that can be abused to keep something under wraps. we'll see 😀
